Abstract

The invention relates to a wafer-like aluminum phosphate / thermosetting resin composite and a preparation method thereof. A preparation process of wafer-like aluminum phosphate comprises the steps of enabling an aluminum-contained compound and a phosphorus-contained compound to react at the temperature of 40-100 DEG C for 10-30min according to the aluminum-to-phosphorus molar ratio of 1:3 to 1:5 to prepare an aluminum dihydrogen phosphate precursor, and then, adding 5.5-17 mol of deionized water to obtain an aluminum dihydrogen phosphate precursor solution; cooling to 0-20 DEG C, regulating the pH value to 4-6 by using an alkaline solution, preserving the heat at the temperature of 0-20 DEG C for 8-12h, and after the reaction is ended, washing, carrying out suction filtration and removing impurities to obtain wafer-like aluminum phosphate with the diameter of 1-1.5mu m; uniformly mixing 100 parts by weight of molten thermosetting resin and 3-50 parts by weight of wafer-like aluminum phosphate, and curing to obtain the wafer-like aluminum phosphate / thermosetting resin composite with flame retardance. The wafer-like aluminum phosphate contains a great number of hydroxyls, has favorable dispersibility in a resin matrix, and also has favorable interfacial force so as to ensure that the composite has a flame retardant effect. The preparation method provided by the invention has the characteristics of wide applicability and simple operation process.

Description

technical field

[0001] The invention relates to a composite material and a preparation method thereof, in particular to an aluminum phosphate / thermosetting resin composite material and a preparation method thereof.

[0002] Background technique

[0003] The rapid development of electronics, energy and other industries puts forward more and higher performance requirements for high-performance resins, among which flame retardancy has become a new necessary performance after heat resistance, dielectric properties and mechanical properties. However, almost all polymers do not have good flame retardancy by themselves, and the addition of flame retardants has been proved to be a simple and feasible method to improve the flame retardancy of polymers.

[0004] In recent years, with the increasing awareness of environmental protection, inorganic flame retardants with high smoke suppression and low toxicity have received widespread attention. At present, such inorganic flame retarda...
